Concept of laser cutting machine

Laser cutting machine is the laser emitted from the laser generator, through the optical system, focusing into a high power density laser beam. The laser beam shines on the surface of the workpiece, so that the workpiece reaches the melting point or boiling point, while the high-pressure gas coaxial with the beam blows away the melted or vaporized metal.With the movement of the relative position of the beam and the workpiece, the material is finally formed into a slit, so as to achieve the purpose of cutting.

Laser cutting processing is to replace the traditional mechanical knife with an invisible beam, with high precision, fast cutting, not limited to cutting pattern restrictions, automatic typesetting to save materials, smooth incision, low processing costs, will gradually improve or replace the traditional metal cutting process equipment. The mechanical part of the laser head has no contact with the workpiece, and will not cause scratches to the surface of the workpiece during work; Laser cutting speed is fast, the incision is clean and smooth, generally no rework is required; The cutting heat affected zone is small, the sheet deformation is small, and the cutting seam is narrow (0.1mm~0.3mm). The incision has no mechanical stress, no shear burrs; High machining precision, good repeatability, no damage to the surface of the material; CNC programming, can process any plane plan, can be a large format of the whole board cutting, no need to open mold, economy and time saving

Compared with the traditional oxy-acetylene, plasma and other cutting processes, laser cutting has the advantages of high speed, small slit, minor heat-affected zone, slit edge perpendicularity, smooth cutting edge, also processing kinds of laser cutting materials, including carbon steel, stainless steel, alloy steel, wood, plastic, rubber, cloth, quartz, ceramics, glass, composite materials and so on. With the rapid development of market economy and the rapid development of science and technology, laser cutting technology has been widely used in automotive, machinery, electricity, hardware and electrical appliances and other fields.
